To all whom it may concern:

Be'it known that I, ERIK O'rro ERIKssoN,

engineer, a subject of the King of Sweden,

residing at Ormbunken, Lidingo-Brevik,

'6 Sweden, have invented certain/new and useful Improvements in or Relating to Air- Cooled Condensers for Locomotives, of

which the following is a specification.

a m locomotives and similar carriages it .10 has previously been suggested to conduct the steam supplied to the condenser through a number of elements preferably consisting of flattened pipes placed side by side and. played upon "by cooling air forced by m'eans Hof fans. a a A This invention relates particularly to condensers of said type but may 'also be applied to air cooled condensers or water cooling apparatus of other types. The object of the 20 invention is to effect such a pla'clng ofthe elements that the condenser may be made of smaller dimensions,particularlyin its longitudinal direction.

To this purpose the elements of the condenser are collecte'd'into groups each con taining several elements placed one "above I v another, the groups being situated in afrow parallel or approximately iparallel to one an other and spaced apart. he invention conare composed of-inclined e emqnts placed vertically-oneabove another, the groups being interconnected by means of plates or the. like so as to cause the cooling air-to pass through 3 the channels formed thereby upwards and 'rearwards, reckoned in the normal running f The greater direction of the locomotive.

the number of elements in each group the smaller is the length of the condenser, since 40 the interspace between the groups necessary oup of elements for the cooling-air of a er than thewidth may. always be taken smal of a group of elements.

The accompanying drawing llustrates an embodiment of the invention applicable to air cooled condensers for locomotives 'in .which the steam passes to the air-cooled condenser as well asto a fluid receptacle which, upon a large .suppl' of waste steam to the condenser, accumu ates steam under vacuum, the receptacle, uponless quantity of steam or no-steam at all being supplied tolected in the larly from greater scale ofthe condenser on line 33 in oups of elements mnmeo-nnn'vrx, swnnmr, ASSIGNOB 'ro AIR-000L131) connnNsER. roe Locomo'rwEs.

the condenser, delivering steam .to the aircooled part which on account thereof nearly alwaysis cooling steam.

and Fig. 2 a partial side view of the same. Fig. 3 is a detailed view on the line 3-3 of Fig. 1 showing the ments into grou s. I

Referring to igs. l and 2, l designates the accumulating fluid receptacle and 2 the air-cooled condenser. steami pipes connecting the fluid receptacle to the steam distributing pipe 4., the steam arrangement of theele- 3 isone of the many" ANGTURBIN, OF STOCKHOLM, SWEDEN, A CORPORA-- passing from the said pipe 4 to the condenser 2 whereit is condensed to water which is-colthe pipes 6 to the fluid receptacle 1. The coollng air is forced through the condenser 2 by the fans 25 about in the direction of the ,arrow 26.

The elements of the condenser are collected into groups,"as will appear-particu- Fig. 3, showing a section to a The elements 11 are in this case arranged parallelin relation to one another and in groups, each group attached to one collecting pipe 12, '13 or 14; The several groups are separated by means of walls 18. These walls may be placed. in various manners depending upon the situation of the elements in the groups. At .all events how-- ever the walls should form channels conduct. ingthe cooling air from the. groups or to the ']same about in the direction of, the arrows '27 the air is divided I In the embodiment shown into parallel currents. 'Figure 3 illustrates how guiding partitions or plates 2O conduct the air assing from the groups of elements rearwar sin re-' lation to the running direction of the locomotive,;thec urrent of air flowing between the plates 20 on account-of the speed of the locomotive. In the same figure 21 denotes a device by means of which said plates may always be directed rearwards independent of the running. direction ofthe locomotive,

the plate 22 being reversed, if desired, autopipes 5 and flows down through matically by the a r pressure to the position 23 shown by stippled lines upon the running 7 direction being contrary to that suppose in the drawing. Fig. 2 illustrates how all 65 1g. 11s a cross-section of the condenser the plates 20 may be reversed for instance from the drivers cabin by pulling or pushing a rod 24-.

Obviously a greater number of elements may be collected into each group than that shown on the drawing. Since the arrangement of the elements in the condenser dew pends upon the requisite room which in case the determined of locomotives is limited by loading gauge, the groups should contain such a number of elements as is necessary in order that the condenser within a limited length shall be of suiiicient size so as to be able to condense the supplied quantity of steam. I

Several modifications of the invention may be imagined without surpassing the scope of the same. Thus the elements may be otherwise shaped as for instance being provided with ribs at the outer side or with enlarged surfaces in any other manner. The elements may also according to the invention be placed in other angular positions than those described above, and the direction of the cooling air may be opposite. The accumulating fluid receptacle can be dispensed within a construction made according to the invention.

What I claim as new and desire to secure by Letters Patent of the United States is 1. An air-cooled condenser for locomotives comprising elements situated close to one another, and means for forcing air through the interspaces between said elements, said elements being collected into groups each containing several elements situated one above another and having an inlet and an outlet common to all elements of said group and adapted to serve only said group, the groups being placed in a row substantially parallel to one another and spaced apart.
